"I have an eurgle 9x radio, same radio as the TGY 9x just rebranded I found the svn for reprogramming the radio. FANTASTIC ! here is more info http://code.google.com/p/er9x/ Earl"

"Hey, you still have any contacts at instructables.com? I need someone who can help to reset my silly pw!!! Their form does not send the code so you can do it yourself! -tks"

"Can you provide a direct link? I can't seem to find the Firecracker on that site. Looks like an excellent platform though!"

"I don't exactly remember which pin it was (it's been two years since I hacked mine), but the FASST receivers all have full PPM output on one pin of the main MCU within it. Some probing with an Oscope should work. Good luck."

"Brad, you can find more technical information from their wiki/repository at http://code.google.com/p/th9x/ There are also links to other similar projects. Check it out.. it's rather good :) And that radio.. Well I have one TGY 9X and also…"

"I'm sure there are some advantages (maybe range), but for what we do, which is constrained to line of sight, I don't see the advantages. There are so many challenges in aerial robotics that reinventing the perfectly serviceable RC…"

"Interesting. I've been reading about the open source "Speck Drum" receiver, which does mixing and such on the receiver instead of the TX. What do you think about that? Also, what do you think about moving from a typical RC radio…"

"PPM is really fast and easy to read for most microprocessors. Autopilots these days tend to have loads of extra digital pins (ArduPilot Mega has 40 spare!) and never enough serial ports, so keeping RC on digital makes sense."
